Detailed Product Description

MDL-120 drill machine has steady performance, high working efficiency, versatility, and it is able to drill in complicated stratum layer and deal with accident. It could perform rotary drilling when equipped with a common alloy drill head and other drill tools to; ordinary globe-tooth drill head could perform impacting rotary drilling on hard rock layer to form a hole rapidly; pipe-following drilling tool is applied to perform sleeving-following for drilling a hole on pebble and gravel when matched with air compressor and air-powered DTH.

Main characters of this drill machine are as followings:
a. Compact structure, full hydraulic pressure control, convenient and flexible operation, easy displacement, good mobility, time-saving, and labor saving.
b. Power head of drill machine has large torque, long stroke, and high drill efficiency which could increase working efficiency and parts of mechanical loading and discharging drill rod could decrease the labor intensity of operators.
c. Equipped with specific drilling tools for pipe-following drilling (drill rod, sleeving, and off-balance bit). Sleeving is applied for protecting wall to drill a hole when the stratum layer is not steady, with high efficiency of drilling and good quality for forming hole.
d. Aiming at special working condition of client in local field, radiating system is optimized to ensure the temperature of hydraulic pressure system is not more than 70^oC, when the outer-door temperature reaches 50^oC.
